Brian Gianforcaro 83fc591cea Kernel: Generate page fault events from the kernel profiler 
Hook the kernel page fault handler and capture page fault events when
the fault has a current thread attached in TLS. We capture the eip and
ebp so we can unwind the stack and locate which pieces of code are
generating the most page faults.
